Embodiment

The each several part that Fig. 1 shows a 3D configurator with the form of schematic diagram---device of design drawing that promptly is used for the design variant of generating structure series---and, information and data stream between these parts, and by the final products of method of the present invention, as to be used to generate design drawing.

One configurator 101 is installed in a unshowned computer system.This configurator 101 is the configuration tools that are designed to man-machine interface, and a SAP/R3 configurator is set up task member inventory 102 by the design variant that this SAP/R3 configurator can be each hope of gear train structural series.For setting up task member inventory 102, configurator 101 access configuration databases 114 store in this configuration database about the information of the member of combiner and can applicable information for what form design variant in structural series about member.

This task member inventory 102 is exemplarily in also explanation hereinafter shown in Fig. 2 a.

At the top of task member inventory 102 are general informations of design variant.In Shuo Ming the example, this general information comprises the numbering that is used to the task of indicating herein, the descriptive keyword of design variant and the information of shaft position.

By means of a plurality of numerals shaft position of encoding, described figure denote is provided with the position of axle head at this.Fig. 8 shows possible position.Show by the different diameters of axle that by Fig. 8

position

0,1 and 2 belongs to input shaft, and

position

3 and 4 belongs to output shaft.Position 0 is used for the input shaft of the bevel gear set of angle transmission mechanism.

Therefore, the task member inventory shown in Fig. 2 a has been described a gear train, and the input shaft of this gear train is arranged on position 2, and the axle of output is arranged on position 4.

Under the top of the task member inventory 102 of Fig. 2 a then is the actual components inventory of form.Member of every row record design variant of form or parts.

This form comprises 7 row:

First row are used to represent every rule purpose row number corresponding comprising.Also can save, mark in order to the present invention will be described for these capable number at this.

Secondary series comprises that form is the information member use characteristic, that use about member.Form shown in Figure 3 furnishes an explanation for each available member use characteristic, and the use of associated components is determined in this explanation.Therefore, form definition shown in Figure 3 one member use characteristic catalogue, this directory stores is in configuration database 114, and is and maintained at this, because configurator 101 is based on this catalogue.Therefore, member use characteristic catalogue is also contained in the member use characteristic that does not have appearance in the current design modification.For example the input shaft in column gear transmission mechanism is parallel usually with output shaft, does not therefore generally use " Fla0 ", " Lag0 " and " Sch0 "; And in the bevel gear level, input shaft is arranged on the position reset among Fig. 8, therefore, must be used for the above-mentioned member use characteristic of these modification with the storage of structure piece number.Store the table of all member use characteristic in configuration database 114, described table is used for setting up task member inventory 102 by configurator 101.

Therefore, for example by the eighth row and the following member use characteristic catalogue of pressing Fig. 3 of the task member inventory of Fig. 2 a---especially 19 row---as seen, six members with structure piece number " 050 " are the bolts that is used on the flange of the axis hole of shaft position " 3 ".

Composition according to combiner, the example of member use characteristic can be: be used for the shell wall split shed closure member, be used for the bolt of closure member, be used for closure member seal, be used for the example that sealing system, housing or the form shown in Figure 3 of a shaft position of determining are mentioned.Described enumerating is non-limit.

The 3rd row of the form of Fig. 2 a comprise the structure piece number of member.Can identify uniquely by these structure piece numbers should be according to the concrete member of given member use characteristic use in design variant.

According to the composition of combiner, with the example of the concrete member of member labelled notation can be: gear with certain number of teeth and certain size; Axle with certain-length, certain diameter and certain material specification (Materialausf ü hrung); Snap head bolt with certain size; Hexagon head bolt with certain size; The case lid of certain feature/shape.Described enumerating is non-limit.

The 4th row of the form shown in Fig. 2 a include the quantity that respective members occurs in design variant.---being the member use characteristic---the identical member of at this, only summarizing its application.Shown in the design variant of example, the structure piece number specifically is to go up each six times at flange " Fla1 " to " Fla4 " for the bolt of " 050 " is mounted 24 times, described flange itself be assigned with member (number) " 040 " or " 041 ".

Whether bright these clauses and subclauses of the 5th tabulation of the form shown in Fig. 2 a relate to CAD parts (being=" 1 ", not=" 0 ").For example handbook " ManEn " and lubricant " oil 1 " are not included in the member among the CAD figure of design variant.Therefore, relevant entry is " 0 " in the 5th row.

Whether bright this member of the 6th tabulation of the form shown in Fig. 2 a relates to wearing terrain (being=" 1 ", not=" 0 ").Can in the CAD drawing, highlight the wearing terrain of design variant by these information.

Which kind of component classification the 7th tabulation bright (associated components) of the form shown in Fig. 2 a is.Setting " 1 " is a part, and " 2 " are assemblies, i.e. one group of part, and " 0 " is other parts.Shown in the design variant of example, lid " 070 " is marked as an assembly, because should form a unit by retaining ring " 080 " and seal " 075 " by lid.Therefore, ring " 080 " is not characterized as being the CAD parts yet, because it has been included among the CAD figure of lid.In another kind of form of implementation, save this row.

In the task member inventory 102 that each can be set up, each member use characteristic occurs once at most.According to combiner, some member use characteristic does not occur in some modification.Structure according to combiner can form various modification, wherein is that different structure piece numbers is specified identical member use characteristic in the member inventory 102 of each modification.

Except information about CAD figure, the single member that task member inventory 102 also the comprises design variant information that how to be mutually related.This information substitution ground can be by means of the diagrammatic representation shown in Fig. 2 b.At this, the node of figure is represented concrete member modification, that pass through relevant structure piece number sign, and the member use characteristic is represented in the sideline.The direction in sideline is obtained by each clauses and subclauses in the explanation in the form shown in Figure 3, especially " is used for " relevant with wherein speech.When by (member) quantity of the table (drawing) of Fig. 2 a greater than 1 the time, in other this quantity that correspondingly marks of node.Member use characteristic " sealing " and " oil " are represented that by the dotted line sideline reason is that member " 075 ", " 080 " and " 070 " are designed to an assembly in the task member inventory shown in Fig. 2 a.Therefore, described member structure intactly is stored as an assembly.

In the figure of Fig. 2 b, also show the additional information of arranging and about attaching parts in design variant about (by the expression shaft position) axle head---as lubricating oil or operation manual---information.Especially lubricating oil and operation manual do not provide in CAD figure.

In conjunction with the tabulation of all member use characteristic of pressing Fig. 3 form, from the information of 1 to 3 row of task member inventory 102, can intactly derive view by Fig. 2 b, wherein, the member use characteristic is stored in this form in " member position number " row.This illustrating property shows that task member inventory 102 includes each the part more information that is assembled into design variant than only listing.Because but the application component use characteristic is to press each position of literal and array, so the member use characteristic also needs " sequence number " in task member inventory 102.Yet it is different with other common sequence number of task member inventory, in (of the present invention) task member inventory---as task member inventory 102---, do not use, but explicitly, entirely accurate quote the required member use characteristic of the concrete modification of formation with each concrete stand-by member from " 1 ", the continuously arranged sequence number in no compartment of terrain.Therefore, described sequence number---is the continuous sequence number that only is used to arrange or quote purpose for other situation---has obtained extra function, promptly indicates the application of associated components in the modification that defines by task member inventory 102.

Figure shown in Fig. 2 b does not comprise loop or circulation.Send a directed sideline at most from each node.This is equivalent to point out unique application for each member use characteristic.The directed edge of figure has been determined directed approach, and these approach terminate on the node " 010 " unlimitedly.The length of approach---quantity of promptly forming the sideline of approach---is different usually: exist length greater than 1 approach, the diameter of figure is also greater than 1.Therefore, clearly, the information in the form of Fig. 2 a is different with the application of template, and members all in template all provide about element body, and therefore the length of all approach all is 1 in corresponding figure.By using diameter greater than 1 figure, can advantageously component composition be become assembly, for example be used for the CAD figure of assembly or be used for making.

As shown in Figure 1, task member inventory 102 is transfused in the load module 105.At this, the form of task member inventory 102 can be printed paper item, be stored on the storage medium or the file on any information carrier.Described input is consistent with corresponding information carrier.

Load module 105 is installed on the unshowned computer system as software algorithm.This load module is by SQI interface 104 visit repository databases 103, and the form with rule in this database is that the member use characteristic is to distributing CAD Associate Command and/or CAD template command.Load module 105 is determined such clauses and subclauses automatically by SQL interface 104 in repository database 103, promptly relevant with task member inventory 102 rule.Determined rule is automatically assessed in load module 105, and---especially CAD standard software---sets up CAD Figure 113 that design variant is shown with assembling form by CAD program 111 by these rules.For these figure, load module 105 visit CAX interfaces 110, this interface loads CAD figure and/or cad data by life cycle management software 109 from basic information database 112, and these figure and/or data are passed to CAD program 111.Load module 105 is visited life cycle management softwares 109 equally by PLM interface 106, thereby provides querying condition data 107 to basic information database 112, or receives Query Result data 108 from basic information database.At this, Query Result data 108 and querying condition data 107 can be stored in arbitrarily on storage medium and/or the information carrier, and are wherein, consistent with mounting medium in information transmission shown in Figure 1.

Device by Fig. 1 comprises at least three databases.The first database form is a basic information database 112, stores the required cad data of CAD figure of the single member of combiner in this first database at least; The second database form is a configuration database 114, and this configuration database is included in the tabulation of all available in structural series member use characteristic at least; The 3rd database form is a repository database 103, wherein storage rule, wherein respectively related two the member use characteristic of each rule.

Before setting up task member inventory 102, at least intactly import repository database 103 for the design variant of wishing.

These data can be combined into a database in principle.Consider for reality, use different standard softwares to come management database respectively, therefore according to the database size physically in addition ground, space database is separated.In this case, take out data advantageously by internet or LAN (Local Area Network) realization to the database transmissions data or from database.

Fig. 4 a/b shows the extracts to the example of repository database.Rule of every row definition of form.The order of rule temporarily is arbitrarily, preferably can structured as requested maintenance knowledge library database.

Each rule just makes in the form two member use characteristic under the indication sequence number---is abbreviated as LfNr1 and LfNr2---interrelated.Determining of firm what a freedom of motion of the associated components of the designated described member use characteristic of each rule description.For rotating for example axle of symmetrical parts, the degree of freedom relevant with symmetry preferably calculated by symmetry, and---for example additional requirement that is directed upwards towards by the rib key study plot that makes axle---is definite.Described definite by means of being listed as: the data of record are carried out in " relation ", " title 1 " and " title 2 ".The rule that relates to the member use characteristic of not quoting in repository database 103 in the task member inventory 102 of Fig. 2 a is compressed in Fig. 4 a/b, to guarantee clearness.

At this, for the title of how much auxiliary views of correlation rule " title 1 " expression, this geometry auxiliary view be defined in combiner each can be assigned with among the CAD figure with the member of the member use characteristic under " LfNr1 ", quoted; " title 2 " is the title of how much auxiliary views of the member use characteristic quoted under " LfNr2 " in a similar fashion.Auxiliary view can be plane, face, also can be crooked---especially physics limit---as surface or boundary surface, limit, and non-rectilinear extends---the especially axis of physics or arrangement, the template of point and rule.

For example Fig. 7 shows member " 040 ", a flange with 3D model 700.Wherein especially be provided with title: cylindrical surface 701 usefulness titles " F_CF_1 " for following auxiliary view, cylindrical surface 703 usefulness " F_CF_3 ", annular surface 702 usefulness " F_PF_1 ", at 3D model 700 dorsal parts and this surface facing surfaces 705 is " F_PF_3 ", and the surface 704 of annular is " F_PF_2 ".In addition, define a template " bolt template ", the bolt hole that wherein belongs to surface 703 is as reference point, and other bolt hole 706 is as signal point (Skizzenpunkt).Because member use characteristic " Fla1 ", " Fla2 ", " Fla3 " and " Fla4 " represent interchangeable parts (referring to Fig. 5) in principle in example, so the title of the auxiliary view that illustrates is identical.

How the feature of the auxiliary view in the 3D model of single member interconnects under confined state at single parts usually.Each auxiliary view all is used for definite freedom of motion physically.

For discontinuous or continuous rotation symmetry member, at first indicate the axis of symmetry or the face of cylinder that is provided with one heart with it.This rotational symmetric member for example is axle, bolt, bearing, seal, spacer sleeve, meshing part or rotational symmetric housing parts.For example, this auxiliary view can be the surface of the axial direction part with constant diameter of axle for axle; For bolt can be the envelope of threaded portion; Can the face of cylinder that the center of the outside surface of inside surface, bearing outer ring of bearing inner race or rolling element is described for bearing; For seal or spacer sleeve can be inside surface or outside surface about radially; For meshing part can be the inside surface of center pit or the face of cylinder of describing point circle, dedendum circle or the pitch circle of engaging piece; For rotational symmetric housing parts can be to be positioned at continuing surface radially inner side, that be used for race ring.Therefore, for example threaded line or the rib key of axle or the engaging tooth of meshing part of bolt can be shown in the drawing that calculate, geometrical feature of this symmetry.

Make these auxiliary views rule related comprise the orientation order for the orientation of forcing a kind of part with other auxiliary view, the order of this orientation relates to the auxiliary view that same rotation designs symmetrically, admittance (this auxiliary view) respective members or admitted by this respective members in this auxiliary view (respective members).For example comprise such pairing:

The inside surface of the outside surface of-shaft part and meshing part, spacer sleeve or race ring, wherein, these inside surfaces are parts of the surface of contact between axle and meshing part, spacer sleeve or race ring;

The envelope of the threaded line of-bolt and confession bolt screw in the inside surface in hole wherein, and the details of bolted threaded line wherein is not shown;

The inside surface in the hole in the radially-outer surface of the annular protrusion the on-case lid and another housing parts, wherein the projection of case lid is placed in the described hole;

The inner radial surface in the outside surface of-bearing outer ring and the hole of housing parts, wherein race ring is placed in the described hole.

Therefore, described pairing relates to rotational symmetric, and these faces contact in the gear train of assembling, perhaps for example represent this surface of contact symmetrically for threaded line or the nearly rotation of rib keyed jointing.

For making rotational symmetric member other member orientation relatively, need the feature of at least one other auxiliary view.For this reason, select one perpendicular to the plane axis of symmetry setting, that describe relative axial position.This plane is described relevant member and is moved to which axial location opposite to each other.Select described plane according to actual stop surface and the surface of contact that occurs in the gear train of assembling.For example, this can be the axial sides that supplies bearing inner race or spacer sleeve to recline of convex shoulder for axle; For bolt can be the carrying plane of bolt head; For bearing can be the axial sides of race ring, and bearing is fixed on the shaft shoulder, interval turns or the housing bore with this side axial; Can be seal for seal be axially fixed in side in the groove with it; Can be spacer sleeve for spacer sleeve be axially fixed in side on meshing part or race ring or the shaft shoulder or the spring washer with it; For meshing part can be the radial zone of the qualification wheel bore of the side of gear hub or side, utilizes this side or radial zone meshing part by being axially fixed with contacting of spacer sleeve, the shaft shoulder, spring washer, stopper ring or race ring; Perhaps for rotational symmetric housing parts can be housing parts on another housing parts carrying plane or be used for the axial medial surface in the hole of bearing seat---be the bottom surface.

Make these auxiliary views rule related comprise the orientation order for the orientation of forcing a kind of part with other auxiliary view, this orientation order relates to another auxiliary plane, wherein, two auxiliary planes contact in the gear train of assembling, perhaps two auxiliary planes have fixing spacing each other in the gear train of assembling, and this spacing is for example predetermined by the extra member that inserts.

If will determine remaining Three Degree Of Freedom in addition for determining fully, for example to allow of the together motion of two members around public rotation, then use such plane for this reason, this plane is described in the surface of contact that is used for fixing in the gear train of assembling, perhaps characterizes fixing geometric configuration required, that rotation is calculated symmetrically.This is the side of pointing to circumferential, as to be used for the rib key forming section or groove for meshing part for example, perhaps upwards shows plane mid-plane, that comprise axis of symmetry, the perhaps osculatory of the position in the flank of tooth in the week of forming section or groove.For shaft joint---be clutch coupling, select one to characterize the composition surface that is used for the power transmission---be the inclined-plane

---axial plane, a perhaps plane that is in the composition surface.

For characterizing the member of non-rotating symmetry, annex for example---as the housing or the case lid of pump, pressure equilibrium container or oil vessel, filtrator, refrigeratory or electronic unit, use the inside surface and a plane of describing the physical support face of described member on another member at least two holes in the member, wherein, described hole is used for erection bolt, admits rivet or pin.

Therefore be apparent that, indicate the auxiliary view that at least one has the clear and definite rotation symmetry axis of symmetry about each member.

The sign auxiliary view is interpreted as, is not the mathematical abstract concept of selecting infinite extension, but therefrom selects limited, the part relevant with scantling for example.

In Fig. 4 a/b " association " row, be that the situation of correlation rule provides the CAD Associate Command for rule, this Associate Command comes spatially related these two auxiliary views by determining two auxiliary views relative motion degree of freedom spatially.The tabulation of possible Associate Command is included in known standard association in the CAD standard software: superimposed, parallel, vertical, tangent, concentric, be separated by with spacing, apply with angle.Can utilize the related orientation relevant further to specialize Associate Command with mutual orientation, wherein can be along orientation ground and anti-orientation ground apportioning cost.But the association of expansion can be set also.

For example the row 123 of the form among Fig. 4 b has been put down in writing a correlation rule, and wherein the member use characteristic is that face " F_PF_1 " and member use characteristic in " Lag4 " member is related for the superimposed ground of the face " F_PF_2 " in the member of " Fla4 ", anti-orientation ground.More precisely, in this example, the bearing of locating to be used for the flange of axis hole at shaft position " 4 " is orientated to respect to described flange,---at this is plane through the side of bearing, and------is flange and plane contacted extension of bearing at this---is superimposed with each other with the face of flange to make the face on the bearing, wherein, bearing is disposed in the fixation side of flange.As shown in Figure 7, the side of bearing is covered by surface 704.

For example, the row 140 of same form has been put down in writing, usage flag is arranged to usage flag concentric for the face of cylinder " F_CF_Zahnrad " of the axle of " Wel2 " for the inside surface---face " F_CF_1 "---of the interstitial hole of the gear of " Zah2 ", wherein, the described face of cylinder is given with the cylindrical surface of contact of gear by axle.

For pattern rule, " title 2 " is the title of the template of appointment in each of combiner is assigned with the CAD figure of the member of member use characteristic " LfNr2 ".It is blank that clauses and subclauses under " title 1 " can keep.

For example 109 records of the pattern rule among Fig. 4 a, the member use characteristic should be installed in the member use characteristic according to the template of title " template is threaded " in the flange of " Fla1 " for the bolt of " Sch1 ".This template is shown in Fig. 6 b: shown in be the snapshot of CAD standard software.At this, initial characteristics 601, bolt is handled with template.The template list 604 of the circular shuttering (Kreismuster) of one description derivation is shown at the left window.That is on a predetermined hexagonal free angle, add the duplicate of bolt, form the feature 602 of masterplateization thus.Correspondingly, in task member inventory 102, quote six bolts " 050 " by member use characteristic " Sch1 ".

Repository database 103 comprises the other explanation to every rule:

The first, in row " WL ", express rule application at which shaft position.Carry out described expression in the above described manner, one of them Null represents that rule application is in all shaft positions.

The second, row " configuration " provide to select which CAD diagram shape.At this, possible values comprises " standard " or " details " or " reduction ", wherein, for example gear is depicted as anodontia right cylinder in " reduction ".The value that can be these row in expansion scheme is freely selected other possibility title.

The 3rd, determine that in row " orientation " association is to be used for determining clearly that at this moment clauses and subclauses are " positions " to member---at this moment clauses and subclauses are " pressures ", still realize the precalculated position---.Using the advantage in precalculated position is to avoid polysemy.Therefore, row " orientation " provide the position of binary attribute, arrange described rule when these row are used in the 3D model of setting up design variant.

The parallel-oriented of for example orthogonal two axles is ambiguity aspect relative orientation.Interim is second orientation by above-mentioned " the 3rd ", is that second orientation may overcome this polysemy by above-mentioned " first " then.

The 4th, row that are used for note are set.At this, these row can be the annotations and comments of the prompting that should occur in the CAD of relevant design modification figure or document or the parameter that keeps for expanding system.

The 5th, row " Aktiv " are set, in these row, can exist logical value " very " or " vacation " in order to activate or the single rule of deactivation.Therefore, can safeguard repository database 103.

Fig. 9 shows the another kind of example of repository database.At this, use Serial No. to indicate the member use characteristic, and be provided with the row that are used for other four parameters.Store geometry auxiliary view and title in row " title 1 " and " title 2 ", wherein the type of how much auxiliary views: " A " is that axle, " F " are the plane for face, " E ".Provide association or masterplate and Associate Command in row " association/masterplate ", wherein type " V " is related, and " M " is masterplate.At least available above-mentioned standard association order is as Associate Command.Therefore, be numbered 2,8,9,10,11 and describe the related of two axles respectively with 12 rule.Regular number 15 the template of bolt is for example described.Because bolt is irrelevant with the layout that inputs or outputs axle, so rule numbers 15 is charged to " 0 " at the shaft position place.Therefore, this rule application is in all shaft positions.For example by considering that the following fact can avoid these clauses and subclauses and obscure mutually according to the shaft position " 0 " that Fig. 8 indicates: provide input shaft and always require to provide output shaft.Therefore, the clauses and subclauses that are made of numeral are a kind of special circumstances.In another embodiment, come mark generality quantifier (Allquantor) by additional character.

Figure 10 shows algorithm that implement, that be used to generate CAD figure in load module 105.

In step 1001, set up structure inventory 1002 by task member inventory 102.One form is provided for this reason, and in this form, each member use characteristic of task member inventory 102---it characterizes CAD parts---is written in the new row.For example the structure inventory 1002 that is drawn by Fig. 2 a is shown in Figure 11.As shown in the figure, in every row except that the member use characteristic also from task member inventory 102 copy number, zone bit " wearing terrain " and quantity, and add initial value be all that 0 numeral " priority ", zone bit " are found ", zone bit " is found the PLM document " and other three row in knowledge base and member inventory.Described numeral is used for classifying to clauses and subclauses at structure inventory 1002 subsequently, and zone bit is used for detecting wrong and finds mistake.

As shown in figure 10, in first loop, continue Processing Structure inventory 1002: in step 1003, select the member use characteristic of uppermost clauses and subclauses in the structure inventory.Uppermost clauses and subclauses are " Geh " in the task member inventory 102 among Fig. 2 a.

Then provide sub-inventory 1005 in step 1004, all such rules of record repository database 103 in this sub-inventory: the first member use characteristic of this rule---promptly is recorded in the member use characteristic under the LfNr1---in dependency rule in repository database 103 be the described member use characteristic of selecting.

For this reason, repository database 103 is designed to SQL database, and has the SQL interface, and load module 105 is by this interface transmission inquiry problem and accept Query Result.

For example, according to the repository database of pressing Fig. 4 a/b, the sub-inventory 1005 of member use characteristic " Geh " be can't help element and is formed, but comprises the rule 108,109 and 110 corresponding to the sub-inventory that is used for " Sch1 ".

In second loop, assess this sub-inventory 1005 below.

In step 1006, select the uppermost clauses and subclauses of sub-inventory 1005.

Whether the second member use characteristic of checking selected rule in inquiry 1007 is included in the structure inventory 1002.This carries out in a loop, in this loop the every capable clauses and subclauses of structure inventory 1002 is checked whether its member use characteristic is consistent with the second member use characteristic of current consideration.

If answer is yes (Y), then should rule relevant with current design variant, and should the number record of rule in structure inventory 1002 in step 1008 at " association " row of the member use characteristic that is used for selecting.The second structure usage flag that on the one hand be current rule in step 1009 increases numeral " priority ", is that two member use characteristic setting zone bits " are found in knowledge base and member inventory " on the other hand.

Perhaps, with the rale store of member in array, and at " association " pointer of the relevant array of record down.

The also template command found of mark in " association " or described array.

The answer is in the negative (N) if inquire 1007, so directly forwards step 1010 to.

In inquiry 1010, check in the sub-inventory 1005 whether have Else Rule.

If (Y) situation of affirming is then gathered in 1011 at next step and is selected ensuing rule from sub-inventory 1005, and forwards step 1007 to.

The answer is in the negative (N) if inquire 1010, then assessed sub-inventory 1005 fully, that is second loop that is through with, and forward step 1012 to.

In inquiry 1012, check and in structure inventory 1002, whether have other clauses and subclauses.

If situation (Y), then from structure inventory 1002, select next member use characteristic and forward step 1004 in 1013 at next step.

The answer is in the negative (N) if inquire 1012, then assessed structure inventory 1002 fully, that is first loop that is through with, and forward step 1014 to.

In step 1014, include the information that provides among Figure 12 according to the structure inventory of the task member inventory 102 of Fig. 2 a.

Check that in inquiry 1014 whether to be each member in the structure inventory all set zone bit and " find " in knowledge base and member inventory.

If then there is the wrong error message that provides in the situation of negating by repository database in step 1022, and stop algorithm.

Answer is yes (Y) if inquire 1014, and then each the member use characteristic for structure inventory 1002 is arranged the association of having write down in step 1015.At this, the value under " orientation " should be in the first place for the rule of " position "; The rule on related face, plane or limit is in second; The rule of associated shaft is in the 3rd; And the rule of description template order is in the 4th.Number arrange according to the rule of ascending order in the regular interior of same levels.This arrangement regulation is drawn in the feature of handling aspect related by used CAD standard software 111.For example, if compare the easier uncertainty that causes of orientation of axle with the orientation on plane, then in structure inventory 1002, the branch time-like is carried out in association and give the preference that the plane is higher than axle.Also advantageously, the capable clauses and subclauses order each other of same levels can be controlled by the arrangement in the member use characteristic catalogue.

In step 1016, come the arrangement architecture inventory according to the descending of digital value in " priority " row.In the clauses and subclauses inside of same levels, as deciding the arrangement of member use characteristic in inventory at form shown in Figure 3 or the storage in configuration database 114 (in proper order).Therefore, in pressing the example of Figure 12, the clauses and subclauses that relate to housing still keep going up most.Perhaps this also can be read by Fig. 2 b, because the sideline all ends at housing, does not send from housing but there is the sideline.But the association of repository database is not necessarily with consistent according to the figure of Fig. 2 b.For example may be advantageously, axle is orientated according to bearing in the axial direction, but the axis of axle is determined with one heart with housing bore.

In the step 1017 of Figure 10, in basic information database 112, search the CAD figure of corresponding structure piece number for each member use characteristic.If there is CAD figure, then in structure inventory 1002 its C_ID of mark number, and set " finding the PLM document " zone bit.

In inquiry 1018, check and whether set all " finding the PLM document " zone bits.If not (N), then finish algorithm and forward corresponding error information 1023 to.

If answer is yes (Y) to inquiring 1018, then all essential data are provided for the assembly drawing of setting up design variant.

Form to finish below in step 1019 and fill in and structure arranged inventory 1002, this structure inventory is shown in the example of Figure 13 consideration.

In step 1020, the clauses and subclauses of structure inventory 1002 are assessed by means of appendage, for the 3D-CAD-model (113,1021,1024,1025) of making design variant.This appendage is integrated in the load module 105 as graphics module, and describes with reference to Figure 14 hereinafter.Especially by graphics module, will in structure inventory 1002, be written in the CAD standard software 111 by the member CAD figure of mark, and with given order, carry out related or handle with template by means of the rule of described record and classification.CAD standard software 111 is set up the 3D model of design variant under the guide of graphics module.

Fig. 6 a and 6b show the example of the view of the cad model of finishing in CAD standard software 111 with the form of screenshot capture.In the left window of display, in Fig. 6 a, provided each association, and the form that provided is the masterplate order of masterplate inventory 604 in Fig. 6 b as related inventory 603 with common form.In related inventory 603, Associate Command 605 can be the standard association order as described above, provides with the member 606 of the one first association member 607 related with second respectively.In described association, housing " 010 " and the flange " 040 " that is used for axis hole at shaft position 4 are superimposed in orientation aspect the auxiliary view, referring to Fig. 2 a and Fig. 3.

Fig. 5 shows the output as 501 CAD figure 3D figure, that make that has the member use characteristic.In the top view of Fig. 5, desalinated cover 502 so that the inside of gear train as seen.

Making the 3D model and the view of deriving is outputed to paper spare 1021, watch-dog 1024 backs or after the 3D model is stored in storage medium 1025, stops algorithm.Can from the 3D model, derive other view by CAD standard software 111, decomposition view for example, cut-open view, detailed view.For deriving cut-open view, preferably on housing parts or other member, define a plane, the cut-open view of hope can be based on this plane.

Figure 14 shows the algorithm of realizing in graphics module.Graphics module visit CAX interface 110 in the first step 1031, then this interface loads the required cad data of 3D module from basic information database 112 to CAD standard software 111.

In 1032, the graphics module of CAD standard software 111 provides the order that assembly is provided at next step.

In 1312, the graphics module of CAD standard software 111 provides the order that uppermost member in the classified structure inventory 1002 is added assembly at next step.

In next step, graphics module checks whether the member in the structure inventory 1002 is marked with association.

If (N) that negate, then graphics module continues the processing of step 1308.If sure (Y), then whether graphics module inspection second member that participates in this association has been added on this assembly.

If (N) that negate, then the graphics module of CAD standard software 111 sends in step 1305 and will participate in the order that the second related member adds assembly.If sure (Y) then directly advances to step 1313.

In step 1313, the graphics module of CAD standard software 111 is given an order: select how much auxiliary views of mark in the relevant association of associated components and carry out the related or possible template command of institute's mark.Therefore, make associated components orientation or fixing about degree of freedom with the dependency rule restriction.

In step 1306, whether the graphics module inspection is the first element numeral Else Rule in structure inventory 1002.If (Y), then select next rule and forward step 1304 to.(N) if not then advances to step 1308.

Therefore, in step 1308, finish quoting association in the structure inventory 1002 at uppermost first member.

In step 1308, graphics module checks in the structure inventory whether quoted other member.If (Y), then select next member, and forward step 1303 to.If not (N), then finished all members, and forwarded step 1310 to.

In step 1310, finished association, and the 3D model 1311 of calculating is finished in output to all members.Output is preferred to be realized by display or other appropriate display device.

Preferably the 3D model 1311 that is calculated is stored in the basic information database 112.

After setting up 3D model 1311, stop graphics module.At this moment, the user for example can add the specific (special) requirements that can not identify, for example design afterwards in configuration, thereby sets up the design drawing of design distinguishingly.

The invention is not restricted to disclosed data layout and data area in instructions and the accompanying drawing.The layout of the row of other form and row, or for example in tabulation, arrange it also is possible, can come the extend information capacity by in every row of form, admitting extra information.Equally, shown form can be merged into an integral array or can be divided into the plurality of sub form.

This is equally applicable to the explanation to data storage and transmission.The form that the invention is not restricted to specify.These forms only for clearer, form view more simply and be selected.Therefore, especially the present invention is being not limited to form used in these figure, layout or coding aspect the storage of the content of figure.

As shown in the above description, the member use characteristic is as the placeholder (Platzhalter) of the concrete member that indicates with the structure piece number.Therefore, the member use characteristic be a kind of with regard to the modification of structural series, provide the mark of the use on definite given position of determining member abstract---the concrete modification that does not just relate to structural series---, therefore be a member position number.Therefore, the member use characteristic has following function: when a member is installed in the position that indicates by the member use characteristic, just use this member in one group of modification.At this, the member that can be assigned with the member use characteristic must have consistent feature.This consistent feature is to be used for member, that must limit at the CAD of associated components figure, how much auxiliary views of typical case at least.For example, such auxiliary view for bolt be the axis of bolt and bolt head under the state of being screwed into contacted of reception part, the perhaps envelope of screw thread and described.Defined auxiliary view is used for determining the locus of member.Then needn't determine these (locus) fully for symmetrical member.

Therefore, according to DIN tentative standard DIN-V 4002-2, member is an object, especially described how much auxiliary views of the feature of this object.In this respect, the member use characteristic is object class (Objectklassen).The member use characteristic advantageously born with technology figure in the relevant task of location number, especially in technology figure to the sign of the member of design variant or assembly.Differently, this member use characteristic or member position number have been expanded the task of common location number, that is same member use characteristic is represented or distributed to the member identical to function in the different designs modification,---for example at the bearing of the axle of determining shaft position or be used for the bolt of the service cover of gear train---with same member use characteristic.

The invention is not restricted to used notion/expression.Described notion is used to illustrate the framework of the data of organizing combiner.Therefore, also can use other conceptual system to describe the present invention.The alternative notion of member use characteristic for example is sequence number or member position number.

The present invention be advantageous in that,, as far as possible as one man finish all process steps with the essential data volume of minimum respectively by considering object class rather than object with feature.

In alternate embodiment, use other data to substitute how much auxiliary views as feature, described feature can be used for the space arrangement between definite two members.

In another embodiment, can set up the CAD figure of other type by load module 105, exploded view for example, with the figure of color mark wearing terrain, two-dimension projection, cut-open view, partial view, functional module or component drawings, described figure simulates the motion of movable link, or checks whether have member overlapping in the conflict check.

In the conflict check, check especially whether each member is overlapping.If then this configuration comprises mistake, the user obtains corresponding prompt.Therefore avoided when assembling the actual physical member subsequently, just finding design mistake.Meshing part but is an exception in this respect, when tooth portion only is depicted as cylinder, for transmitting torque must make described meshing part overlaid.At this, perhaps suppress the error message of meshing part when overlapping, perhaps insert the view of engagement and make each meshing part around its axis of symmetry rotation, until reaching cooperation---that is tooth engagement effectively physically, wherein, do not have then output error message of the result of cooperation after turning over 360 °, wherein, the meshing part that has matched moves together, just move together to keep correct tooth engagement around separately axis, promptly associated teeth is meshing with each other according to the rules.

If there is the gear train engaging structure, wherein tooth portion is meshing with each other routinely, then or by corresponding rule realize, perhaps cooperate by determining continuously as described above, in another embodiment on the 3D model with the function of picture specification and/or simulation gear train.

In another embodiment, set up assembly instructions according to the order of association.For this reason, correspondingly arrange the rule in the repository database 103, and correspondingly define the member use characteristic.Especially avoid, point in directed sideline shown in the figure shown in Fig. 2 b can not be approaching member.Therefore like this arrange, promptly this figure as among Fig. 2 b from inside to outside, show assemble sequence on the contrary with directed sideline.

As mentioned below, in another embodiment, at this moment determine the order of demounting procedure automatically by the 3D model gear train modification, in computer system of hope.For this reason, at first activate the collision detection function of 3D-CAD standard software.At this moment, remove the orientation order in succession, wherein, after each is removed separately, check: whether can remove associated components by ensuring escapement from confliction.At this, before releasing---being deactivation---relates to the orientation order on the rotational symmetric member axis or the face of cylinder, at first remove the orientation order that relates to the sagittal plane on this member.Can remove the orientation order that relates to axial plane at last.The order that the assembling capacity of each member is checked is abideed by above-mentioned definite " priority ", but reversed in order here, reason is that for example bolt can easily be pulled down from housing, but housing can not separate with a plurality of coupled members in a step.Therefore, the member that has minimum " priority " value from member (the perhaps member use characteristic under the member).If conflict check finds that member can take out from gear train by removing the sagittal plane, then remove the circumferential orientation of coaxial orientation and possible reservation, this member of record in arranging inventory.At this moment, continue (operation) remaining gear train in described mode.

Alternatively or auxiliary ground, for determining disassembly sequence such as above-mentioned the arrangement of using the member use characteristic.

If gear train is splitted into single-piece fully,---to be the order of demounting procedure---be transferred to the control module 1501 of manufacturing equipment shown in Figure 15 1500 with then determined arrangement inventory, wherein, this control module 1501 is by operation circuit 1502 at least one operating control 1503 of control.These control module 1501 control operating controls 1503, make operating control 1503 utilize gripping tool 1505 physics that movably are fixed on the hinged mechanical arm 1504 to grasp the member 1507 that is positioned at storeroom 1506 with the order opposite practically, and place it in the given position of 3D model this member with disassembly sequence.Figure 15 exemplarily shows one 1508 of should install, a gear 1509 and a case lid 1510.Substitute storeroom 1506, also member 1506 can be remained in the high rack warehouse, operating control 1503 is provided with the shelf operating control.Housing matrix 1511 from determining again according to right of priority numeral.When adding or mate member 1507, control module is considered the bulk of installation component, and determines conflict free approach, and operating control 1503 is transferred to its precalculated position along this approach with current member 1508,1509,1510.By previous disassembly sequence that determine, that at this moment carry out, guarantee to exist such approach in opposite mode.Be to determine for example to be used for the clamping torque of bolt, utilize additionally or store or be stored in the relevant rule with concrete member the indication of---for example the row in Fig. 9 " Param1 " are in " Param4 "---relatively.

In a kind of improvement project, be used to set up the preceding method of 3D model except that can on control module 1501, carrying out, control module 1501 also has input media 1513, for example, import the rule of repository database 103 at least by this input media by the reading device of keyboard, mouse or batch storer; By output unit 1512, for example writing station and/or other visual device of monitor, printer, accurate drawing printer, batch storer are exported the 3D model of finishing assembling at least.

In order for example to set up the knowledge base be used for making furniture, the sign of the auxiliary view of member according to (following principle), is made the member that rectangle mainly occurs by the combiner of furniture parts.At this, described sign also can be according to the surface of contact of reality appearance.For example should be mutually on the bonding squarely plank for forming drawer wall or housing at two, on two members, mark an end face respectively in this wise, one side and a seamed edge face, make that align with an end face of another member or be consistent in a side of a member in rigging position, each seamed edge face then is in the common plane.Be fixing metal accessory onboard, two holes that the hole inner concentric of feature and plank is provided with inboard and the plane of describing hardware carrying plane onboard.

Can advantageously use the 3D-CAD system---as Solidworks or Inventor---as the CAD standard software.But also can advantageously use data by Wikipedia, the German version, keyword is " Liste mechanischer ", on November 29th, 2006, the known 3D-CAD standard software of the version of 12:26.

Utilization is by the method for design drawing of the present invention, as to be used to generate design variant, wherein, this design variant is made up of the member of combiner, especially utilizes computer system, is identified for setting up the CAD figure of design variant or the command sequence of 3D model according to the member inventory of design variant.For describing the application of member in design variant, allocation member use characteristic in the member inventory.
